Is not working, until I get it updated you can use this version.
Thanks Weasel!
For LibreOffice users having problems("Input must be whole positive number" error) I recommended to open the file and save it in ods format.
After that it should work, at least it did for me.
The file works fine in excel and openoffice (now apache).
Made a change so SP score works with Openoffice/Libre.
